UNTTEn STATES PATENT FFICEQ NELSON GREEN, OF \VATERFORD, ONTARIO, CANADA.

REAPlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 248,736, dated October 25, 1881.

Application filed January 25, 1881. (ModeL) To all whom it may concern Be it known that I, NELSON GREEN, of the village of \Vaterford, in the county of Norfolk, in the Province of Ontario, Canada, agricultural-implement maker, have invented new and useful Improvements in Reaping-lVIachines, of which the following is a specification.

My invention relates to that class of reaping-machines having a rolling rake-head 0perated by a tripping device; and it consists, among other things, in attaching the rake-head rigidly to a spindle supported on double bearings in the rake-arm, which is specially constructed as hereinafter described for the purpose, the spindle being arranged to work endwise in its bearings and operated by a sliding tripping-block, hereinafter more particularly explained.

In the drawings, Figure l is a perspective view of the rake-jack. Fig. 2 is a detail of the rake-jack bed. Figs. 3, 4, 5, and 6 are details of the rake arm and head.

In the drawings, A is a rake-arm, pivoted in the usual manner to the rake-wheel B.

G is a rake-head, pinned or otherwise rigidly fastened to the spindle D. The projecting end of the spindle D fits into a longitudinal hole in the rake-arm A, which hole constitutes the inner bearing for this spindle, an outer bearing beingtormed at A by the extension of the arm A, as represented. The rake-head G is provided with lugs I), through which the spindle D passes. A spiral spring, E, is placed upon the spindle D, one of its ends pressing against the inner lug, 1), its other against the outer hearing, A, producing sufficient pressure to hold the rake-head in position till tripped, as hereinafter explained.

A tripping-dog, F, is bolted to the inside of the rake-head O, the bolt securingit thereon being arranged to hold at the same time a steel plate, d, on the projection a (see Fig. 3) on the inside of the rake-head, between it and the projection e on the rake-arm, which projection is provided with a similar steel plate.

It will be noticed that the outer hearing, A, of rake-arm A is provided with a projection, Z), to correspond and come in contact with a similar projection, I), on the outer end ofthe rake-head 0. These projections, inconnec tion with similar projections, to e, on the inner rake-head will be appreciated by all who are familiar with the operation of this class ofreaping-machincs, while the advantage of having an outer projection, I), as well as an inner one, a, to hold the rakehead in a vertical position, is so apparentthat itis not necessary to enlarge upon it in the specification.

The device I provide for tripping my rake head consists in a sliding block, H, suitably held in the bed-plate G. Behind the sliding block H, I hinge, in suitable lugs on the bedplatc G, a lever, I, so weighted that when the block is placed forward it falls behind it and holds it in that position. The weighted lever I is connected by suitable rods and levers to a hand or foot lever within easy reach of the driver, who can thus raise this hinged lever clear of the block, permitting the block to be broughtback byaspringatt-ached toitbelowthe plate G out of the way of the dog on the rakehead. When the block H is thus thrown back by the driver the tripping-dog F comes in contact with a pivoted lever, K. This lever is pivoted to the bed-plate G, and has a tail,f, which, when the lever K is thrown back, as described, comes in contact with a notch in the block H, throwing it forward into its original position.

It will be noticed that the weighted lever I is provided with an adjustable end, 6, whose shank screws into the end of the lever I, for the purpose of lengthening or shortening this lever, in order to alter the point at which the tripping-block will turn up the rakes. This is accomplished by bringing the rubbing portion of the block H nearer to or farther from the lover I, so as to trip the rake-head sooner or later, as may be desired.

In order that more or less dip may be given as required to the rakes, I secure the rake-jack to the bed G by a king-bolt, L, and adjustingbolt M,passing through an arm,O, and a slotted lug, N, on the bed-plate, permitting a limited motion to the bolt M when the jack is turned upon its king-bolt L, for the purpose of imparting to the rake the dip required.

The difl'erent parts having been properly adjusted, each rake-head as it reaches the block H is caused to dip or roll by its tripping-dog F striking against the rubbing-rib on the block H, which causes the rake-head to move outwardly against the thrust of the spring E until the lugs b and d have moved past the lugs b and e of the rake-arm, when the friction and pressure of the lower edge of the rake-head against the spring J, fastened to the bed-plate G, causes it to turn in its bearings. As soon as the rakeheads pass the end of the spring J they resume their former position.

What I claim as my illVGlltlOll is 1. A tubular rake-arm, A, hinged at its inner end to the rake-wheel13,and provided with an extension, A, to inclose the spring E, and with an outer bearing, A, in combination with the spindle D, to which the rake-head is secured, one end of said spindle sliding in the tubular arm A, substantially as and for the purpose specified.

2. The spindle D, secured to the rake-head O, and supported in double bearings by the rake-arm A, as described, in combination with the inclosed spring E, for pressing the rakehead 0 toward the rake-arn1 A, substantially as and for the purpose specified.

3. Aslidingblock,H,provided with aretracting-spring, in combination with the weighted lever I, pivotedat one end to lugs of the bedplate G, and having at its other end an adjustable head, i, and connected by suitable rods and levers to a foot orhand lever within reach of the driver, and operating substantially as and for the purpose specified.

4. A rake-head, U, provided with a trippingdog, F, in combination with the sliding block H, spring J, weighted adjustable lever I, and pivoted lever K, operating substantially as and for the purpose specified.

5. A rake-head, O, provided with a trippingdog, F, in combination with the pivoted lever K and sliding block H, operating substantially as and for the purpose specified.

6. A rake-jack pivoted on the king-bolt L, and forming a bearing and support for the rake-wlieel B, and provided with an arm, 0, in combination with the adjusting-bolt M, bedplate G, and the slotted lug N on said bedplate, substantially as and for the purpose described.
